Fix api-ref for access rules

The key for access rule metadata in the API
request or response is just "metadata".

The "access_key" in /share-access-rules
endpoint responses doesn't need to specify
a min-version since its present in all API
versions that the endpoint itself is supported
with.

TrivialFix
